Plenary Lecture 1

New Product Development, Multi-BOARD – From Idea to Prototype

Professor Mihaiela Iliescu Research & Development Department

SC OPTOELECTRONICA-2001 SA ROMANIA

E-mail: iomi@clicknet.ro

Abstract: There is the opportunity of new product development when a customer need, or market opportunity are estimated and, consequently sales and profit are expected. The steps followed in order to get from idea generation to prototype demonstration are evidenced. Aspects of strategic marketing, project management, as long as manufacturing of main component elements are evidenced by this lecture so, that, finally, a demonstration of how does the Multi-BOARD prototype work is offered.
